The invention relates to the field of medicine, can be used in the practice of dentistry.

There are a number of diseases, which shows surgery on the tissues of the tongue. These include malignant tumors and tumor-like processes, trauma, burns, etc. Relevant, in our opinion, is the treatment of cancer of the tongue. Tongue cancer is from 40 to 70% of malignant tumors of the oral cavity. The number of men among patients with cancer of the tongue 2-3 times the number of women. The age of patients ranges from 20 to 80 years, mean age 50 years (according to who). The most common to date the type of surgical interventions for cancer of the tongue is hemiglossectomy (half resection language). For the first time this operation was performed by Dane Pimperhell in 1916. This operation entails serious violations of vital functions: speech, eating, and injure the psyche of patients [1]. These patients experience difficulty in chewing, because for the formation of physiologically correct food to lump you have to put more time and effort. The function of speech affected by disruption vukobratovi and sound pronunciation, because the remaining half of the language takes an uncharacteristic normal position and not fully fills the entire volume of articulatory movement is deposits. For the speedy recovery of language functions for patients assigned to complex miogymnastics that includes exercises for self-training of the muscles of the tongue and the hardware method. Often tumor process tissues language combined with oncological processes in the bone tissue, including the upper jaw. Can also be combined lesions of the tissues of the tongue and hard tissues of the maxillofacial area (firearms and pellet wounds, burns and injuries). To replace the missing part of the upper jaw, giving soft tissue support and repair functions of chewing, breathing and speech data of patients are shown resection prosthesis in the upper jaw. Thus, there is a relatively large group of patients with combined pathology of the tissues of the tongue and tissues of the maxillofacial area. In the case when the patient required resection prosthesis in the upper jaw, and to restore the chewing function and speech complex miogymnastics language, we propose to combine resection prosthesis in the upper jaw, having in its composition artificial palate or palatal retainer plate with removable individual replaceable biogeneticists element.

Among the known devices closest to the claimed is vestibular plate Myrrh with bead, which is shown in the presence of harmful Pref is check thumb sucking, biting the lower lip, and muscle weakness of the maxillofacial region - muscles of tongue and circular muscle of the mouth (Dr. Hinz Dental Co.)[2]. This unit (analog) is used in dairy and removable bites, consists of extraoral rings, lip bumper, the process for fixing the beads and beads to eliminate dullness lingual muscles and the placement of the tongue in the correct position. Also known apparatus proposed by M. A. Danilova, E. A. Zalazaeva, C. A. Bronnikov [3]. This apparatus consists of a lip bumper, extraoral rings, which is still connected with the outer surface of lip bumper along the lines of closing the lips, the process of wire to secure the beads, permanently United with the inner surface of lip bumper and having three bending, located on each side of the beads, Nakonechny ground, still connected to Hubnik bumper and hood on the incisors of the lower jaw, permanently United with Nakonechny Playground.

Drawbacks of the device, in our opinion, are the standard sizes (use only in dairy and removable bites), same location and could not be replaced biogeneticists element (beads on a wire), standard trajectory and the diameter of the beads, the impossibility of the simultaneous combination of prosthetics and correction of postoperative dis the functions of language.

The purpose of the invention: development of removable lamellar resection prosthesis of the upper jaw with removable biogeneticists element.

Goal is achieved by the combination of the removable resection prosthesis and removable individually replaceable biogeneticists element. The invention is illustrated in the diagram in which Fig.1 is a view of the prosthesis at the top.

The prosthesis consists of a locking part, which includes the fixing plate 1 and the system klammern fixation on the remaining teeth 2; resection of part 3, which is directly in contact with the remaining tissues of the upper jaw and forms a prosthetic bed for the permanent prosthetic appliance; and a removable, individual, replaceable biogeneticists element (SISMA), representing orthodontic wires with different cross-sections 4, curved for each patient individually, with a sliding her multifaceted bead of variable diameter 5. Biogenetically element is installed on the period jogimatti in the base of the prosthesis. In places fixation of SISMA prosthetic base thicken, making a special plastic flows. Fixation was performed in blind holes 6 by the tension of the wire element. On resection of part of dentures are artificial teeth 7, made of plastic. Patients are given advice to try to touch on is ucinki and move it along the trajectory, marked wire. Time jogimatti 2-3 hours a day, the rest of the time the patient uses his prosthesis without biogeneticists element. With the improvement and increase of the amount of tongue movement biogenetically element is replaced by a new one with a more complex trajectory and a bead of smaller diameter. These manipulations are carried out until then, until the compensatory restoration functions of language in sufficient volume. After the treatment of the blind hole is closed with self-hardening plastic and produce polished.

Example. The patient Century. 1945 R. addressed in the base dental clinic GBOU VPO "Ryazgmu of the RF Ministry of health at the Department of prosthetic dentistry and orthodontics with complaints about the inconvenience of chewing, speech, aesthetic defect. From history: previously underwent surgery for resection of half of the upper jaw, combined with resection of half of tongue malignant neoplasm.

The patient was solved to make the resection prosthesis of the upper jaw with biogeneticists element. The patient was provided orthopedic treatment with further clinical observation. Recommendations for an integrated jogimatti using biogeneticists element.

After partial recovery volumes magic cube MOV is I changed the trajectory of biogeneticists element to recover full compensatory amount of tongue movement. The volume of traffic was restored.

Thus, the use of the proposed removable resection prosthesis of the upper jaw with biogeneticists element gives the opportunity to spend quality prosthetics and accelerate the rehabilitation period in these patients and improve quality of life.
